It's a glitch in Zarx264GUI 2.0, one of recent Quick Time versions broke it so you will need to either uninstall QuickTime, encode to MKV and then recontainer the output to MP4 (using MKVtoMP4 or something similar), or use the older version, which can be found here. Alternatively you could try downgrading Quick Time, but I have no idea what the last "safe" version is...
